我创建了一个用户控件:
<UserControl ...>
<Grid DataContext="{Binding UserContrlViewModel>
<Grid Width="200" Height="100" RenderTransformOrigin="0.5,0.5">
<Grid.Resources>
<Storyboard x:Key="zoomIn">
<DoubleAnimation
Storyboard.TargetProperty="ScaleTransform.ScaleX"
From="0"
To="1"
Duration="0:0:1" />
<DoubleAnimation
Storyboard.TargetProperty="ScaleTransform.ScaleY"
From="0"
To="1"
Duration="0:0:1" />
</Storyboard>
</Grid.Resources>
<Grid.RenderTransform>
<ScaleTransform />
</Grid.RenderTransform>
<Grid.Style>
<Style TargetType="Grid">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsActive}" Value="True">
<DataTrigger.EnterActions>
<BeginStoryboard>
<StaticResource ResourceKey="zoomIn" />
</BeginStoryboard>
</DataTrigger.EnterActions>
</DataTrigger>
</Style.Triggers>
</Style>
</Grid.Style>
<TextBlock Width="60" Text="Input" />
<TextBox Width="80" Margin="80,0,0,0" />
</Grid>
...
</Grid>
</UserControl>
我想要实现的是当用户控件的视图模型类的IsActive属性设置为true时,运行zoomIn动画.这个动画应该放大网格里面的内容.当我触发动画时,我收到以下错误消息:
Cannot resolve all property references in the property path ‘ScaleTransform.ScaleX’. Verify that applicable objects support the properties.
我的动画有什么问题?我该如何实现所描述的放大动画?谢谢.
最佳答案 我知道了:
>< ScaleTransform>应该具有< ScaleTransform ScaleX =“0.5”ScaleY =“0.5”/>性能
例如,设置为使缩放从50%开始.
>在第一个< DoubleAnimation>中Storyboard.TargetProperty属性的值
应该从“ScaleTransform.ScaleX”更改为“RenderTransform.ScaleX”.
>在第二个< DoubleAnimation> Storyboard.TargetProperty属性的值
应该从“ScaleTransform.ScaleY”更改为“RenderTransform.ScaleY”.
